Abstract (en)
[origin: EP2506453A1] A wireless relay device includes: a first receiving channel configured to receive signals from a base station or from a base station and a terminal, a second receiving channel configured to receive signals from the terminal, a first sending channel configured to send signals to the base station or to the base station and the terminal, and a second sending channel configured to send signals to the terminal, and further includes a radio frequency control unit configured to, during communicating with the base station and the terminal, control the first receiving channel, the second receiving channel, the first sending channel and the second sending channel to use frequency bands in the following mode: receiving signals synchronously from the base station and the terminal in a first time interval, and sending signals synchronously to the base station and the terminal in a second time interval, wherein the third frequency band and the fifth frequency band are two guard bands between the working frequency band of a Frequency Division Duplex (FDD) system and the second frequency band serving as the working frequency band of a Time Division Duplex (TDD) system. The disclosure realizes the bidirectional relay communication between the base station and the terminal by using an idle guard band, increasing the utilization efficiency and the utilization flexibility of the guard band.
